Description

Volume setting method and device of Bluetooth headset and electronic equipment

Technical Field

The present disclosure relates to the field of portable listening devices, and in particular, to a method and an apparatus for setting a volume of a bluetooth headset, and an electronic device.

Background

The earphone is a pair of conversion units for receiving an electrical signal from a media player or receiver and converting it into audible sound waves using a speaker proximate to the ear. At present, earphone can divide into wired earphone and wireless earphone, and wherein wired earphone needs about two earphones to constitute through wired connected mode and control the channel, produces the stereophonic effect, wears inconveniently. The wireless earphone communicates with the terminal through a wireless communication protocol, such as Bluetooth (BT), which has the characteristics of no need of data line collection and convenient use compared with the wired earphone.

Bluetooth is a wireless communication technology supporting short-range communication between devices, and has been widely used in the field of wireless communication. In the prior art, a wireless communication channel can be established between two devices supporting the bluetooth technology to realize data transmission. Taking a bluetooth headset and a bluetooth master device such as a mobile phone or a display device as an example, the process of establishing a wireless communication channel between the two devices can be divided into a discovery pairing phase and a connection communication phase.

Detailed Description

For the purposes of making the objects, technical solutions and advantages of the exemplary embodiments of the present application more apparent, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is apparent that the described exemplary embodiments are only some embodiments of the present application, but not all embodiments.

The embodiment of the application provides a method and a device for setting the volume of a Bluetooth headset, and the method and the device can be at least applied to a double-hardware-system display device with a camera. The following is a detailed description of the display device.

For convenience of use, various external device interfaces are usually provided on the display device, so as to connect different peripheral devices or cables to realize corresponding functions. When the high-definition camera is connected to the interface of the display device, if the hardware system of the display device does not have the hardware interface of the high-pixel camera for receiving the source code, the data received by the camera cannot be presented on the display screen of the display device.

Also, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resource, and usually only supports video decoding with a resolution of 4K at maximum, so when video chat while watching the network television is to be implemented, in order not to reduce the definition of the network video picture, it is necessary to decode the network video using the hard decoding resource (typically, GPU in the hardware system), and in this case, only the video chat picture can be processed in such a way that the video is soft decoded by a general processor (e.g. CPU) in the hardware system.

The soft decoding is adopted to process the video chat pictures, so that the data processing load of the CPU is greatly increased, and when the data processing load of the CPU is too heavy, the problems of picture blocking or unsmooth can occur. Furthermore, due to the data processing capability of the CPU, when the video chat frame is processed by adopting the soft decoding of the CPU, the multi-channel video call cannot be realized, and when the user wants to perform video chat with a plurality of other users at the same time in the same chat scene, the situation of access blocking occurs.

Based on the above-mentioned aspects, to overcome the above-mentioned drawbacks, the present application discloses a dual hardware system architecture to implement multiple video chat data (at least one local video).

The concepts related to the present application will be described with reference to the accompanying drawings. It should be noted that the following descriptions of the concepts are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application.

Optionally, the presentation of different view display areas has priority difference, and the display priorities of the view display areas are different among the view display areas with different priorities. If the priority of the system layer is higher than that of the application layer, when the user uses the acquisition selector and the picture switching in the application layer, the picture display of the view display area of the system layer is not blocked; and when the size and the position of the view display area of the application layer are changed according to the selection of the user, the size and the position of the view display area of the system layer are not affected.

The same level of display may be presented, in which case the selector may switch between the first view display region and the second view display region, and the size and position of the second view display region may change as the size and position of the first view display region changes.

Since separate operating systems may be installed in the a chip and the N chip, there are two independent but interrelated subsystems in the display device 200. For example, android (Android) and various types of APP can be independently installed on the chip A and the chip N, so that each chip can realize a certain function, and the chip A and the chip N can cooperatively realize a certain function.

And then, the Bluetooth master device sends a pairing request to the Bluetooth slave device, the pairing key is carried in the pairing request, and when the Bluetooth slave device determines that the pairing key is correct, a pairing success response message is fed back to the Bluetooth master device so as to complete Bluetooth pairing. An application program in the Bluetooth master device sends a connection establishment request message to the Bluetooth slave device, and the Bluetooth slave device returns a connection response message to establish a communication channel. The bluetooth slave device then uses the established communication channel to send data to the application in the bluetooth master device to complete the data interaction.

Fig. 10 is an application scenario diagram of the embodiment of the present application, where, as shown in fig. 10, a bluetooth headset establishes a communication connection with a display device having a bluetooth function, and the display device transmits media data to a bluetooth headset end through the established communication link to realize sound output. It will be appreciated that one display device may be connected to a plurality of different types of bluetooth headset, or that one bluetooth headset may be connected to a plurality of different display devices. In different scenarios, the user may choose to use different bluetooth headsets. In the scenario shown in fig. 10, the display device is a bluetooth master device and the bluetooth headset is a bluetooth slave device.

It can be understood that the method for automatically setting the volume of the bluetooth headset provided by the embodiment of the present application may be a method executed by a bluetooth master device, that is, an execution subject of the method of the present application may be a processor in the bluetooth master device. In a specific implementation, the method provided in this embodiment may be implemented by a processor in the bluetooth master device executing a corresponding computer application. Of course, in other embodiments, the method for automatically setting the volume of the bluetooth headset provided in the embodiments of the present application may be performed by the bluetooth headset that is a bluetooth slave device, that is, the main body of performing the method of the present application may be a processor in the bluetooth headset. In a specific implementation, the method provided in this embodiment may be implemented by a processor in the bluetooth headset executing a corresponding computer application.

When the Bluetooth headset is successfully connected with the corresponding Bluetooth master device, the Bluetooth master device can receive a connection message INFO sent by the Bluetooth headset. By detecting whether the connection message INFO sent by the bluetooth headset is received, it can be detected whether the connection with the bluetooth headset has been successful. And when the connection between the Bluetooth master device and the Bluetooth headset is detected to be successful, namely, a connection message INFO sent by the Bluetooth headset is received, the use information of the Bluetooth headset is acquired.

The usage information of the bluetooth headset includes a unique identification of the bluetooth headset and usage scenario information. The unique identifier may specifically be a MAC (Media Access Control ) address of the bluetooth device. The MAC address of the bluetooth headset may be obtained when the bluetooth master initiates pairing with the bluetooth headset. The usage scenario information includes at least one of environmental noise information, motion information, light intensity information, user voice information, and application information connected to the Bluetooth headset or a combination of a plurality of pieces of information therein. The environmental noise information, the action information and the light intensity information can be collected through a sound sensor, an acceleration sensor or a gyroscope and a light sensor which are arranged on the Bluetooth headset. The user voice information may be obtained by a microphone of the bluetooth headset or by a microphone device on the bluetooth master device, and the user voice information may specifically be scene limiting information input by the user to the bluetooth master device or the bluetooth headset, for example, the user speaks into a voice assistant on the bluetooth master device: the voice information of the user is scene limiting information, and the Bluetooth headset using scene limited by the user can be obtained by analyzing the voice information of the user.

It should be noted that, the usage scenario information of the bluetooth headset may be a combination of any of several information such as environmental noise information, action information, light intensity information, user voice information (scene limiting information), and application program information, so as to implement multidimensional description of the usage scenario of the bluetooth headset. The noisy degree of the surrounding environment of the user can be identified through the environment noise information, the motion state of the user can be identified through the action information, whether the user is stationary, fast running, jogging or the like, whether the user is in a night sleep state currently can be identified through the light intensity information, and specific matters such as voice call, song listening, video watching and the like can be identified through the application program information.

Illustratively, the usage scenario of a bluetooth headset may be described by the following information: ambient noise (a particular parameter value) +action (a particular parameter value such as movement speed and/or acceleration) +light intensity (a particular light intensity value) +user speech semantics+application name. Among these, applications are typically sources of audio media data, such as QQ music, internet music, himalaya, and the like.

As shown in tables 1 and 2, when a specific parameter or specific content corresponding to any one of the above information parameters is changed, it means that the usage scenario of the bluetooth headset is changed. Wherein "1", "1#" and "1#" represent different values, semantics or names, respectively.

TABLE 1

Scene(s)	Ambient noise	Action	Light intensity	User speech semantics	Application program
						Scene 1	Parameter 1	Parameter 1	Parameter 1	Mode 1	Application 1
Scene 2	Parameter 1 #)	Parameter 1	Parameter 1 #)	Mode 1	Application 1
						…	…	…	…	…	…
Scene n-1	Parameter 1	Parameter 1#	Parameter 1#	Mode 1	Application 1#
						Scene n	Parameter 1#	Parameter 1 #)	Parameter 1# # # #)	Mode 1#	Using 1#

TABLE 2

Scene(s)	Action	Light intensity	Application program
				Scene 1	Parameter 1	Parameter 1	Application 1
Scene 2	Parameter 1	Parameter 1 #)	Application 1
				…	…	…	…
Scene n-1	Parameter 1#	Parameter 1#	Application 1#
				Scene n	Parameter 1 #)	Parameter 1# # # #)	Using 1#

It can be seen that, through carrying out the multidimensional description to bluetooth headset's use scene, realize further accurate division to headset use scene, for example, through action parameter's difference, can further subdivide the running scene into fast running scene and jogging scene. Through the accurate division to the use scene to make each scene of refining correspond to the custom volume value of a user, can be finer, accurate to bluetooth headset's volume setting, and then promote user experience.

Step 902, judging whether a habit sound value corresponding to the acquired use information exists according to the acquired use information and the pre-stored correspondence between the use information and the habit sound value.

When the embodiment of the application is specifically implemented, the corresponding relation between some usage information and the custom sound value is pre-stored, and the corresponding relation is established when a new item of usage information is acquired each time. Wherein, for each acquired unique identification and usage scenario information, when any item of the unique identification and usage scenario information does not coincide with the stored information, the acquired device information and usage scenario information are regarded as a new item of usage information. When the acquired usage information is judged to be new usage information, waiting for a preset time period, such as 1min, acquiring a usage volume value of the Bluetooth headset after the preset time period, taking the usage volume value as a habit volume value, establishing a corresponding relation between the usage volume value and the new usage information, and storing the usage volume value.

After a group of new use information and corresponding habit volume values are acquired, the method saves the corresponding relation between the use information and the habit volume values, so that the user habit volume values of the specific Bluetooth headset under the specific use scene can be automatically memorized, and the problem that the volume set in the last connection cannot be memorized due to the introduction of the initial volume setting function of the current Bluetooth headset is solved.

When the embodiment of the present application is specifically implemented, the correspondence between the custom sound value and the usage information may be saved by the structure shown in table 3.

TABLE 3 Table 3

As can be seen intuitively from table 3, even though the usage scenario is the same, if the connected bluetooth headset is different, the corresponding custom volume values may also be different, e.g. MAC1 and scene 4 correspond to volume 4, and MAC2 and scene 4 correspond to volume 8. This is because the power amplifier capability of different bluetooth headsets varies, so when the habit volume values are matched, the method of the embodiment also identifies the unique identifier of the connected bluetooth headsets, so as to distinguish different bluetooth headsets and set corresponding habit volume values for the different bluetooth headsets.

Therefore, by adopting the implementation mode, not only the habit volume value of the user is corresponding to the specific use scene of the Bluetooth headset, but also the habit volume value is corresponding to the use scene and the specific Bluetooth headset, and in each corresponding relation, the equipment, the use scene and the habit volume value are in one-to-one correspondence, so that the corresponding habit volume values can be set for the user according to different scenes, different Bluetooth headsets can be distinguished, and the influence of the power amplification capability spread of the different Bluetooth headsets on the actual volume of the headset is eliminated.

In step 902, the unique identifier and the usage scenario information in the obtained usage information are compared and matched with the stored unique identifier and usage scenario information one by one, so as to determine whether a habit sound value corresponding to the obtained usage information exists. If the acquired usage information is completely matched with the stored usage information, the habit sound value corresponding to the usage information can be found from the stored corresponding relation. Wherein, the complete matching means that the unique identification of the device is consistent with the stored unique identifier, and each parameter in the usage scenario information is matched with the stored parameter.

It should be noted that "matching" in this embodiment of the present application includes that two parameters to be compared are completely identical or the difference value thereof is within a preset range.

Step 903, if there is a habit sound value corresponding to the acquired usage information, setting the habit sound value to the sound volume of the bluetooth headset.

When the habit volume value corresponding to the currently acquired use information exists in the stored corresponding relation, the volume of the Bluetooth headset can be directly set to be the corresponding habit volume value, so that the automatic setting of the volume of the Bluetooth headset is realized, the problems of too small volume or complicated manual operation are avoided, and the user experience is improved.

If it is determined in step 902 that there is no habit sound value corresponding to the acquired usage information, it is indicated that the usage information acquired this time is new usage information, and in this case, step 904 is performed after step 902.

Specifically, in step 904, the usage volume value of the bluetooth headset is obtained after the preset time period, and the usage volume value is used as a custom volume value, so as to establish a corresponding relationship between the usage volume value and the obtained usage information, and save the corresponding relationship.

Therefore, through step 904, more corresponding relations between the usage information and the custom sound values can be continuously expanded, so that the corresponding relations stored locally are more comprehensive, and the corresponding custom sound values can be conveniently set for different Bluetooth headsets under different scenes.

Fig. 11 is a flowchart of another embodiment of a method for automatically setting the volume of a bluetooth headset according to the present application. As shown in fig. 11, the method may include:

and step 111, when the connection of the Bluetooth master device and the Bluetooth headset is detected to be successful, acquiring the use information of the Bluetooth headset, wherein the use information comprises the unique identification and the use scene information of the Bluetooth headset.

For example, the acquired unique identifier of the bluetooth headset is MAC1, and the usage scenario information is scenario 3. The scene 3 is a scene described by at least one or a combination of a plurality of environmental noise information, action information, light intensity information, user voice information and application program information connected with the Bluetooth headset.

Step 112, judging whether a habit sound value corresponding to the acquired use information exists according to the acquired use information and the pre-stored correspondence between the use information and the habit sound value.

Following the example described in step 111, a habit sound value corresponding to the acquired usage information "MAC1, scene 3" may be found to be "sound volume 5" according to table 1.

And step 113, if a habit sound volume value corresponding to the acquired use information exists, setting the sound volume of the Bluetooth headset as the habit sound volume value.

The embodiment described in step 112 is followed, i.e. the volume of the bluetooth headset is set to "volume 5".

Step 114, monitor whether a volume value adjustment event has occurred.

In the process of the Bluetooth headset communicating with the Bluetooth master device, the Bluetooth headset can use the functions provided by the AV RCP protocol to reversely control the volume or media of the Bluetooth master device. Wherein, the volume is reversely controlled by increasing or decreasing the volume, and the media is reversely controlled by switching the audio source, stopping playing or starting playing, etc.

When the user adjusts the volume of the Bluetooth master device through the key on the Bluetooth headset, or directly adjusts the volume on the Bluetooth master device, a volume value adjusting event is generated.

For example, the user adjusts "volume 5" set in step 113 to "volume 5#" by a key on the bluetooth headset.

And step 115, if yes, acquiring an adjusted volume value, and updating the corresponding relation between the use information and the habit volume value by using the adjusted volume value.

When the occurrence of a volume adjustment event is monitored, an adjusted volume value or a current volume value is obtained, and the corresponding relation between the use information and the habit volume value is updated by using the adjusted volume value. In specific implementation, the habitual volume value in the original corresponding relation is replaced by the adjusted volume value so as to update the original corresponding relation.

Along with the above example, the habit volume values corresponding to the usage information "MAC1, scene 3" in table 1 are modified from "volume 5" to "volume 5#".

Based on the embodiment shown in fig. 11, in another embodiment of the present application, after step 113, the method may further include:

step 116, monitor whether a scene change event has occurred.

Since in the embodiment of the application, the usage scenario of the bluetooth headset is described by usage scenario information, specifically, one or a combination of several of environmental noise information, motion information, light intensity information, user voice information, and application information connected to the bluetooth headset, when any one of these information changes, it is regarded that a scenario switch occurs.

In the specific implementation, environmental noise information, action information and light intensity information are collected in real time through various sensors arranged on the Bluetooth headset, the change condition of parameters corresponding to each item of information is analyzed, and for each item of information, when the parameters change or the change amplitude exceeds a preset range, a scene switching event is generated.

In addition, when the Bluetooth earphone or the microphone device on the Bluetooth main equipment collects user voice information actively input by a user and the semantic content is scene limiting information, whether the semantic content is consistent with the scene limiting information corresponding to the current scene is judged, and if the semantic content is inconsistent with the scene limiting information, a scene switching event is generated.

In addition, a scene change event is generated when a change in an application program that is a source of media data is detected.

Step 117, if a scene switching event occurs, judging whether a corresponding relation to which the usage information containing the usage scene information after switching belongs exists in the stored corresponding relation; if not, step 118 is performed, and if so, step 119 is performed.

Since the usage information includes the unique identifier of the bluetooth headset and the usage scenario information, the occurrence of the scenario switching event means that the usage scenario information changes, that is, the usage information changes, and thus it is necessary to re-determine whether there is a correspondence relationship to which the changed usage information belongs in the stored correspondence relationship.

For example, it is assumed that the usage scenario information before the occurrence of the scenario switching event is "scenario 3", and if the usage scenario information after switching is "scenario 4", the usage information is changed from "MAC1 and scenario 3" to "MAC1 and scenario 4", where "MAC1 and scenario 4" are the usage scenario information after switching. As can be seen from table 1, there is a correspondence relationship to which the post-switching use scenario information belongs in the stored correspondence relationship, the custom sound value corresponding to the correspondence relationship is "sound volume 4", and if the post-switching use scenario information is "scenario 5", there is no correspondence relationship to which the post-switching use scenario information belongs in the stored correspondence relationship as can be seen from table 1.

Step 118, if not, after the preset duration of the scene switching event occurs, acquiring a usage volume value of the bluetooth headset, taking the acquired volume value as a custom volume value, establishing a corresponding relation between usage information including the switched usage scene information and the current volume value, and storing the usage volume value.

For example, the usage scenario information after switching is "scenario 5", after a preset duration occurs in the scenario switching event, the usage volume value of the bluetooth headset is "volume 9", and then the corresponding relationship between "MAC1, scenario 5" and "volume 9" is established and stored.

Step 119, if yes, updating the corresponding relation of the usage information containing the switched scene information by using the current volume value of the Bluetooth headset; or, adjusting the current volume value of the Bluetooth headset to a habit volume value corresponding to the usage information containing the switched scene information.

If it is determined in step 117 that there is a correspondence to which the usage information including the usage scenario information after the switching belongs in the stored correspondence, two possible cases are included: firstly, in the corresponding relation, a habit volume value corresponding to the use information is consistent with a current volume value of the Bluetooth headset; and secondly, the habit sound value corresponding to the use information is not consistent with the current sound value of the Bluetooth headset.

For the second case, the current volume value of the bluetooth headset may be adjusted to the habitual volume value in the correspondence, or the habitual volume value in the correspondence may be modified to the current volume value of the bluetooth headset by step 119.

For example, assuming that the usage information including the usage scenario information after switching is "MAC1, scenario 4", where "scenario 4" is the scenario after switching, it may be determined according to table 1 that the correspondence relationship to which "MAC1, scenario 4" belongs exists in the stored correspondence relationship. In this case, it is assumed that the current volume value of the bluetooth headset is "volume 10", i.e., belongs to the second case described above. At this time, in step 309, the volume of the bluetooth headset may be adjusted from the current "volume 10" to "volume 4" corresponding to "MAC1, scene 4"; alternatively, "volume 4" corresponding to "MAC1, scene 4" is modified to correspond to "volume 10".

It should be noted that, when the embodiment of the present application is specifically implemented, the steps executed in step 309 may be determined in combination with actual needs.

As can be seen from the above technical solution, the embodiments of the present application provide a method for setting the volume of a bluetooth headset, when it is detected that a bluetooth master device is successfully connected with the bluetooth headset, obtaining usage information of the bluetooth headset, where the usage information includes a unique identifier of the bluetooth headset and usage scenario information; judging whether a habit volume value corresponding to the acquired use information exists or not according to the acquired use information and the corresponding relation between the pre-stored use information and the habit volume value; if there is a custom volume value corresponding to the acquired usage information, the volume of the Bluetooth headset is set to the custom volume value.
